Sorry about that, I have fixed the link.
Thanks about the audio quality. I use a M-Audio MicroTrack 24/96 with a pair of M-Audio Aries powered condenser mics. You have to be careful with condenser mics, in general, because they pick up everything. I got them more for one on one interviewing but think they do OK double duty for this sort of event recording. The Aries have an internal shock mount and in general seemed to be engineered specifically for field recording.
What really made the difference on this audio was some judicious use of SoundSoap and the Levelating. The former helps eliminate the unwanted elements the condenser mics pick up. The latter helps compensate for mic placement, with two mics for six speakers, distance varied widely.
